Before & After

There's a home improvement project taking place on a midcentury modern dwelling every day: A Rummer in Southwest Portland's Garden Home neighborhood or Beaverton's Oak Hills. A ranch-style house in Hillsdale or another version of the low-profile, high-style design in Milwaukie or Lake Oswego.

But nowhere in the world is restoring midcentury architecture taking place on a grander scale than in the Southern California's Coachella Valley, inarguable the greatest depository of 1960s swank.

From October through mid-April, members of the Palm Springs Historical Society escort visitors on walking tours of "Mad Men"-era architecture.

Oregonians attending Palm Springs Modernism Week, Feb. 16-26, will be able to go inside some of the rehabbed homes once owned by celebrities, tennis pros and golfers.
